Fusion

STRING allows inspection of the interaction evidence for any given network. Choose any of the viewers above (disabled if not applicable in your network).

Nodes:

Network nodes represent proteins

splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.

Node Color

colored nodes:query proteins and first shell of interactors

white nodes:second shell of interactors

Node Content

empty nodes:proteins of unknown 3D structure

filled nodes:some 3D structure is known or predicted

Edges:

Edges represent protein-protein associations

associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.

Known Interactions

from curated databases

experimentally determined

Predicted Interactions

gene neighborhood

gene fusions

gene co-occurrence

Others

textmining

co-expression

protein homology

STP2

Transcription factor, activated by proteolytic processing in response to signals from the SPS sensor system for external amino acids; activates transcription of amino acid permease genes; Transcription factor involved in the regulation of gene expression in response to extracellular amino acid levels. Synthesized as latent cytoplasmic precursor, which, upon a signal initiated by the plasma membrane SPS (SSY1-PTR3-SSY5) amino acid sensor system, becomes proteolytically activated and relocates to the nucleus, where it induces the expression of SPS-sensor- regulated genes, including the a [...] (541 aa)

Predicted Functional Partners:

SSY5

Serine protease of SPS plasma membrane amino acid sensor system (Ssy1p-Ptr3p-Ssy5p); contains an inhibitory domain that dissociates in response to extracellular amino acids, freeing a catalytic domain to activate transcription factor Stp1p; Protease component of the SPS-sensor system, which regulates the expression of several amino acid-metabolizing enzymes and amino acid- and peptide-permeases in response to extracellular amino acid levels by controlling the activity of two transcription factors, STP1 and STP2. Catalyzes the activation of these transcription factors, which are synthes [...] (699 aa)
